Getting an object two move between two objects continuously
I'm making a game where my Goal needs to move back and forth between two walls. I've tried troubleshooting this for hours but still can't find a good way of doing this. If someone could please explain some steps needed to make this happen I would be really grateful. It needs to 1.Move 2.When hitting wall go the opposite direction on the x axis 3.continue doing this until level is finished
Try something like this:
Int direction = 1;
public Rigidbody RB;
void Start ()
{
RB.velocity = //way you want it to go
}
void FixedUpdate()
{
//Do stuff
}
void OnCollisionEnter(Collision cool)
{
//First check if the object hit your wall
//If it did then do this
direction*=-1;
RB.velocity = //vector3 * direction;
}
same answer, using kinematics, we cant use colliders to detect walls and the solution isn't elegant like the previous, I just encourage read it to learn other way, but use the @ray2yar as final solution, more general purpose (I just suggest, in case your later don't have perfect aligned walls change direction*=-1; by direction = -cool.GetContact(0).normal)
Vector3 wallPosition1;
Vector3 wallPosition2;
float ballSpeed;
float wayCompleted = 0;
float step;
bool inveseWay = false;
void Start(){
//Get the step to do each FixedUpdate
step = (ballSpeed*Time.FixedDeltaTime) / (wallPosition2 - wallPosition1).magnitude;
}
void FixedUpdate()
{
transform.positon = Vector3.Lerp (wallPosition1, wallPosition2, wayCompleted);
if (inveseWay){
wayCompleted -= step;
if (wayCompleted < 0){
wayCompleted = 0;
inveseWay = false;
}
}else{
wayCompleted += step;
if (1 < wayCompleted ){
wayCompleted = 1;
inveseWay = true;
}
}
}
